Detailed ways

Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one

In view of the problems existing in the prior art, in the load balancing process, Embodiment 1 of the present invention provides a load balancing method, as shown in FIG. 1 , the method may include the following steps:

Step 101, the base station equipment obtains the user selection policy configured by the operator.

In the embodiment of the present invention, in the specific implementation process, the operator can configure the user selection strategy on the OMC (Operation Maintenance Center, operation and maintenance center), and the base station device can obtain the user selection strategy configured by the operator from the OMC. For example, the base station device sends a request message for requesting the user to select a policy to the OMC, and the OMC notifies the base station device of the user selection policy configured by the operator after receiving the request message for requesting the user to select a policy.

Step 102 , when the network load of the local cell reaches a preset load threshold, the base station equipment uses the user selection strategy (ie, the user selection strategy configured by the operator) to select users to be migrated from the local cell.

Step 103, the base station device migrates the user to be migrated from the current cell to another target cell.

Specifically, in the process of calculating the load evaluation value of load balancing, the base station equipment estimates the load of the cell, and when the network load of the cell reaches a preset load threshold, it is determined that the cell is currently in a high load state. Afterwards, during load balancing inter-cell load information interaction, the base station equipment interacts with neighboring base stations to obtain the load status of neighboring cells through X2 information. When the load of neighboring cells is light, the base station device can select neighboring cells as the target cell. Afterwards, in the load balancing process of selecting users to be migrated, in the embodiment of the present invention, the base station equipment needs to use the user selection policy configured by the operator to select users to be migrated from the local cell. Afterwards, in the load balancing process of load migration of the users to be migrated, the base station equipment migrates the users to be migrated from the current cell to other target cells.

In a preferred implementation of the embodiment of the present invention, the user selection policy configured by the operator specifically includes but is not limited to one or any combination of the following: a user selection policy that prohibits frequent migration of users; based on QCI (QoS Class Identifier, quality of service level indication) User selection strategy for business type; user selection strategy based on user load evaluation value; user selection strategy based on user location information.

Case 1. When the user selection policy is a user selection policy that prohibits frequent migration of users, the base station equipment uses the user selection policy to select the user to be migrated from the local cell, including but not limited to the following selection methods: when the user migrates to the base station When the device is in its own cell, the base station equipment sets a protection timer for the user; before the protection timer expires, the user is not allowed to be selected as the user to be migrated; after the protection timer expires, the user is allowed to be selected as the user to be migrated .

Specifically, if the user has just migrated to the local cell of the base station equipment, the user is migrated to another target cell again, which will affect the experience of the user. Based on this, in the embodiment of the present invention, when a user migrates to the local cell of the base station equipment due to reasons such as load balancing or coverage, the base station equipment can identify the user through the information element in the X2 handover request signaling (the X2 handover request The signaling carries the cell identity and user information of the base station equipment before migration), and sets the protection timer for the user. Before the protection timer expires, the user is not allowed to be selected as the user to be migrated; after the protection timer expires, the user is allowed to be selected as the user to be migrated. Wherein, the timeout period of the protection timer can be arbitrarily configured by the operator, for example, it is configured as 30s. Based on the above-mentioned user selection policy that prohibits frequent migration of users, the service experience of the user can be guaranteed, and the number of switching times of the user can be reduced.

Case 2: When the user selection policy is based on the QCI service type, the base station equipment uses the user selection policy to select the process of users to be migrated from the cell, including but not limited to the following selection methods: the base station equipment determines that the operator allows Migrated QCI service type (configured in the user selection policy), when the user's service is the QCI service type allowed by the operator, the user is allowed to be selected as the user to be migrated; when the user's service is not the QCI service allowed by the operator Type, it is not allowed to select this user as the user to be migrated. Or, the base station device determines the QCI service type that the operator does not allow migration (configured in the user selection policy), and when the user's business is a QCI service type that the operator does not allow migration, the user is not allowed to be selected as the user to be migrated; When the user's service is not a QCI service type that is not allowed to be migrated by the operator, the user is allowed to be selected as the user to be migrated.

Specifically, for voice services and other QCI service types that are sensitive to delay and dropped calls, the number of handovers of these users should be reduced as much as possible. Based on this, in the embodiment of the present invention, the operator can configure QCI service types that do not allow migration and/or QCI service types that allow migration in the user selection policy according to service policy requirements. For example, an interface identifier is reserved for the QCI service type to identify whether migration is allowed for the QCI service type. For example, when the interface identifier of the QCI service type is 1, it means that the QCI service type is a QCI service type that does not allow migration; when the interface identifier of the QCI service type is 0, it indicates that the QCI service type is a QCI service type that allows migration. Further, when the user's business is a QCI service type that is not allowed to be migrated by the operator, the user is not allowed to be selected as the user to be migrated; Migrate users. Based on the user selection policy based on the above QCI service type, the operator can configure which QCI service types to switch, so as to ensure that the experience of users of certain specific QCI service types is improved. For example, the above manner can avoid the migration of users of QCI service types such as voice services.

Case 3: When the user selection strategy is the user selection strategy based on the user load evaluation value, the base station equipment uses the user selection strategy to select the user to be migrated from the cell, including but not limited to the following selection methods: the base station equipment determines the user's When the user's load evaluation value is greater than the preset evaluation value threshold, the user is allowed to be selected as the user to be migrated; when the user's load evaluation value is not greater than the preset evaluation value threshold, the user is not allowed to be selected as the user to be migrated Migrate users.

Specifically, in order to reduce the number of switching users, the operator can also configure a user selection policy based on user load evaluation values, and configure a preset evaluation value threshold based on actual conditions. Based on this, only when the user's load evaluation value exceeds the preset evaluation value threshold, the user is allowed to be selected as the user to be migrated; when the user's load evaluation value is not greater than the preset evaluation value threshold, the user is not allowed to be selected as the Users to be migrated. Wherein, according to the load balance evaluation algorithm, the base station equipment can obtain the uplink load evaluation value and the downlink load evaluation value of each user, therefore, the operator can configure the preset uplink evaluation value threshold and the preset downlink evaluation value threshold. When the user's uplink load evaluation value exceeds the preset uplink evaluation value threshold, and/or the user's downlink load evaluation value exceeds the preset downlink evaluation value threshold, the user is allowed to be selected as the user to be migrated; otherwise, the selection will not be allowed This user is the user to be migrated. Based on the above user selection strategy based on the user load evaluation value, the number of handover users can be effectively reduced, the additional overhead of air interface signaling, and the probability of handover failure can be reduced.

Situation 4: When the user selection strategy is a user selection strategy based on user location information, the base station device uses the user selection strategy to select the user to be migrated from the cell, including but not limited to the following selection methods: the base station device determines the user's location information, and when the location information of the user is located in the specified location of the cell, the user is allowed to be selected as the user to be migrated; when the location information of the user is not located in the specified location of the cell, the user is not allowed to be selected as the user to be migrated.

Specifically, if the user at the edge of the cell performs a handover based on load balancing, it may switch back to the base station equipment again due to reasons such as coverage, resulting in a ping-pong handover. Based on this, the operator can configure the user in the center of the cell to perform handover based on load balancing. Therefore, the operator configures the location of the cell center as the designated location of the cell. When the location of the user is located in the designated location of the cell, it is allowed to select the user as User to be migrated; when the user's location is not located in the designated location of the cell, the user is not allowed to be selected as the user to be migrated, so that the user in the center of the cell is switched based on load balancing. Based on the above user selection policy based on user location information, ping-pong switching can be avoided.

In the embodiment of the present invention, when the user selection strategy configured by the operator is multiple user selection strategies, each user selection strategy will also have different priorities; The user's process, including but not limited to the following methods:

The base station equipment selects the first group of users to be migrated from the local cell by using the user selection strategy with the highest priority. If the number of users in the first group of users to be migrated is not greater than the number of users to be migrated finally, the base station device determines that each user to be migrated in the first group of users to be migrated is the final user to be migrated. Further, if the number of users in the first group of users to be migrated is less than the number of users to be finally migrated, the base station device can also select users from the cell to ensure that the number of users in the first group of users to be migrated is the same as the number of users selected in the cell. The sum of the number of users is the number of users who are finally migrated.

If the number of users in the first group of users to be migrated is greater than the number of users to be migrated finally, the base station device selects the second group of users to be migrated from the first group of users to be migrated by using the user selection strategy of the next priority. If the number of users in the second group of users to be migrated is not greater than the number of users to be migrated finally, the base station device determines that each user to be migrated in the second group of users to be migrated is the final user to be migrated. Further, if the number of users in the second group of users to be migrated is less than the number of users to be finally migrated, the base station device can also select users from the first group of users to be migrated, so as to ensure that the number of users in the second group of users to be migrated is the same as the number of users in the first group of users to be migrated. The sum of the selected users in a group of users to be migrated is the final number of migrated users.

If the number of users in the second group of users to be migrated is greater than the number of users to be migrated finally, the base station device also needs to use the user selection strategy of the next priority to select the third group of users to be migrated from the second group of users to be migrated; By analogy, until the base station equipment selects the final user to be migrated.

The above selection process will be described in detail below in conjunction with a specific application scenario.

When the user selection policy configured by the operator includes a user selection policy that prohibits frequent user migration, a user selection policy based on QCI service types, a user selection policy based on user load evaluation values, and a user selection policy based on user location information, and prohibits users from frequently The priority of the migrated user selection policy is higher than that based on the QCI service type. The priority of the user selection policy based on the QCI service type is higher than that based on the user load evaluation value. The user selection policy based on the user load evaluation value is When the priority of the policy is higher than the user selection policy based on user location information, the base station equipment uses the user selection policy to select the user to be migrated from the cell, including:

The base station equipment selects the first group of users to be migrated from the cell by using the user selection strategy that prohibits frequent migration of users; in the process of selecting the first group of users to be migrated, when the user migrates to the cell, the base station device sets the protection timing for the user Before the protection timer expires, the user is not allowed to be selected as the user to be migrated; after the protection timer expires, the user is allowed to be selected as the user to be migrated.

If the number of users in the first group of users to be migrated is not greater than the number of users to be migrated finally, the base station device determines that each user to be migrated in the first group of users to be migrated is the final user to be migrated. Further, if the number of users in the first group of users to be migrated is less than the number of users to be migrated finally, the base station device can also arbitrarily select users from this cell to ensure that the number of users in the first group of users to be migrated is the same as that of users from this cell The sum of the number of users selected in is the number of users to be migrated.

If the number of users in the first group of users to be migrated is greater than the number of users to be migrated finally, the base station equipment uses a user selection strategy based on the QCI service type to select the second group of users to be migrated from the first group of users to be migrated; During the process of grouping users to be migrated, when the user's service is a QCI service type that the operator allows for migration, it is allowed to select the user as the user to be migrated; when the user's service is not a QCI service type that the operator allows for migration, it is not allowed to select the user is the user to be migrated.

If the number of users in the second group of users to be migrated is not greater than the number of users to be migrated finally, the base station device determines that each user to be migrated in the second group of users to be migrated is the final user to be migrated. Further, if the number of users in the second group of users to be migrated is less than the number of users to be finally migrated, the base station device can also select users from the first group of users to be migrated, so as to ensure that the number of users in the second group of users to be migrated is the same as the number of users in the first group of users to be migrated. The sum of the selected users in a group of users to be migrated is the final number of migrated users.

If the number of users in the second group of users to be migrated is greater than the number of users to be migrated finally, the base station equipment uses a user selection strategy based on the user load evaluation value to select a third group of users to be migrated from the second group of users to be migrated; During the process of three groups of users to be migrated, when the user's load evaluation value is greater than the preset evaluation value threshold, the user is allowed to be selected as the user to be migrated; when the user's load evaluation value is not greater than the preset evaluation value threshold, the user is not allowed to be selected is the user to be migrated.

If the number of users in the third group of users to be migrated is not greater than the number of users to be migrated finally, the base station device determines that each user to be migrated in the third group of users to be migrated is the final user to be migrated. Further, if the number of users in the third group of users to be migrated is less than the number of users to be finally migrated, the base station device can also select users from the second group of users to be migrated, so as to ensure that the number of users in the third group of users to be migrated is the same as the number of users in the first group of users to be migrated. The sum of the selected users in the two groups of users to be migrated is the final number of migrated users.

If the number of users in the third group of users to be migrated is greater than the number of users to be migrated finally, the base station equipment uses a user selection strategy based on user location information to select a fourth group of users to be migrated from the third group of users to be migrated; In the process of grouping users to be migrated, when the user's location information is located in the specified location of the cell, the user is allowed to be selected as the user to be migrated; when the user's location information is not located in the specified location of the cell, the user is not allowed to be selected as the user to be migrated user.

If the number of users in the fourth group of users to be migrated is not greater than the number of users to be migrated finally, the base station device determines that each user to be migrated in the fourth group of users to be migrated is the final user to be migrated. Further, if the number of users in the fourth group of users to be migrated is less than the number of users to be finally migrated, the base station device can also select users from the third group of users to be migrated, so as to ensure that the number of users in the fourth group of users to be migrated is the same as the number of users in the fourth group of users to be migrated The sum of the selected users in the three groups of users to be migrated is the final number of migrated users.

If the number of users in the fourth group of users to be migrated is greater than the number of users to be finally migrated, the base station device may also select the final user to be migrated from the fourth group of users to be migrated.

The processing of combinations of other user selection strategies and user selection strategies under other priorities is the same as the processing of the above combination of user selection strategies, and will not be repeated here.
